STAIR ROD.

Application led August 17, 1925. Serial No. 50,571.

This invention relates to improvements in stair rods, and has for one of its principal objects the provision of a rod for stairs or the like, which shall be adapted to maintain and retain in proper position a carpet or other cover which is applied to the stair.

One of the important objects of this invention is to provide a stair rod which can be readily applied to a staircase or the like with a View to maintainingr the stair cover in proper osition and without the use of nails or tac s.

Still another important object of this invention is the provision, in a stair rod, of 16 means for securely maintaining the stair cover in desired position both as regards to the horizontal and vertical proportions ot the steps themselves, and even with respect to any overhanging edges of the stairway.

Still another and further object of this invention is to provide, in a stair rod or the like, means whereby the same may be conveniently adapted to staircases of varying widths, and further, to staircases ascending between vertical walls or devoid of such vertical walls.

Other and further important objects of the invention will be apparent from the disclosures in the accompanying drawings and following specification.

The invention, in a preferred form, is illustrated in the drawings and hereinafter more fully described.

In the drawings:

Figure 1 is a perspective `view illustrating a series of steps having a stair cover thereon, and with the improved stair rod of this invention applied thereto.

Figure 2 is a similar perspective view,

illustratinglr a staircase ascending between side walls, and having the cover maintained in position by a modification of the present invention.

Figure 3 is a detail view, partsl being a broken away, of the stair rod illustrated in Figure l.

Figure 4 is a detail view of the rod illustrated in Figure 2.

Figure is a partial sectional view of the rod shown in Figure 3. Figure is a partial sectional view of the rod shown in Figure 5.

As shown in the drawings:

The reference numeral 10 indicates generally a rod in the form of a cylinder, which constitutes the main portion of the stair rod of this invention, and which has telescopically mounted therein a, corresponding rod element o1* tube 12. As best shown in F igures 3 and f1, a suitable stop device 14 is 60 provided 011 the element 12, and extending through al slot 16 in the member l() so as to limit the extensibility of the device to any desired or convenient extent.

The modification illustrated in Figures 3 65 and 5 embodies in the end of each tube 10 and 12 a suitable L-shaped retaining member 18, the bent-over end of which is adapted. to (zo-operate with the side of a stair case wall 20 illustrated in Figure 1. A suitable 70 helical spring 22, adapted to be placed under tension, is mounted in the tube 1() and has one end affixed to the end of the tube 1,2 so that the device itselt can beV suitably clamped in position on the staircase 20.

In the modification illustrated in Figures 4l and 6 the L-shaped retaining members 18 are replaced by pointed projections 24 mounted in the ends of the members 10 and 12, which points are adapted to penetrate slightly the side walls of a staircase 26, as best illustrated in Figure 2.

In this modification a helical spring 28 is provided adapted to be placed under compression when the steering rod is mounted in position.

()n each of the modifications aflixed ad-` ditional corporate retaining members in the4v form of cent 1ally pivoted retaining elements 3() adapted to be mo'lmted in position 90 against the vertical face of' the steps and thereby maintain the carpet in desired relation thereto, as best illustrated in Figures 1 and 2.

I am aware that many changes may be made and numerous details of construction the retaining means in desired position, sind additional means on the stair iod foi' Yeiti ally retaining the stair eoifei in position against the i'ziee oit :i` step, smid mezins iiiehiding rotatable cover gripping supporte4 pivotziliy mounted on the retaining: eiements.

In testimony whereof I :iiiix my signature,
